Factors to Consider When Buying a Side Imaging Fish Finder


Your Boat

If you think you can just buy any kind of fish finder, you are wrong. Not all devices work on every kind of boat. Some are more suited for others. If you buy the wrong one, it’s either you buy a different one or have it modified.


Screen Features

The wider the screen, the better. If you choose to have a bigger screen, the information and details it will display will be easier to view. The resolution will also make the display clearer and easier to read. This is important because you will be looking at the device to see your surroundings.



Some units come with a transducer while some do not. A transducer is important for fish finders because it is the one that determines the location of the fish and shows it to your device. If the fish finder you choose already comes with one, then that is convenient. If it doesn’t, then you will have to purchase a compatible one separately.



Compared to traditional sonars, Side Imaging is better at showing your underwater surroundings. It gives you more details and locates more fishes. Side Imaging devices have more coverage and have clearer detection. It will be able to determine whether what’s near you are fish, objects, or structures.

If you plan to upgrade your fish finding technology, Side Imaging fish finders are the way to go. In this article are some of the best out there in the market. Hopefully, this will guide you to an easier decision-making.
